Patented Feb. 39, 1931 Are HENRY G. ONSTAID, OF MINNEAPOLIS, MINNESOTA,ASSIG-NOR TO EEG-LES CONSTRUC- TION COMPANY LIMITED, OF MINNEAPOLIS,MINNESOTA LOADING-SPOUT DEVICE Application filed March 23, 1929. SerialNo. 349,356.

My invention relates to leading spo vices, and while intended more parfor use as a dock SpOllt for loudiz or other material into boats frombuildings or bins located on docks, it will be understood that it issusceptible of use for loading grain or other material into other conters such as freight cars. An object of the is to provide a devi v ofthis 0 which both the incli otion and the the spout may be varied asdesired 0 effect the loading operation to the best advantage.

Another object is to provide power operated means whereby theinclination of the spout may be readily yariz-zl and to provideindepci'idently controllable power operated means whereby the length ofthe spout may be read ily varied. Another object is to so construct bothof the power-operated mechanisms that the spout will retain the positioninto which it is adjusted both in regard to inclination and length untilone or both of the mechanisms are again operated for changing the seting of the spout.

The full objects and advantages of my invention will. appear inconnection with the detailed description thereof, and the novel featuresof my inven ive idea will be particularly pointed out in the claims.

In the accompanying drawings which illustrate a practi il embodiment ofmy inveiv tion, Fig.1 is a. sectional clc ational View showing thedelivery end of the spout positioned zibove a boat. Fig. 2 an enlargediew in horizontal section on the line 2 2 of Fig. 1. Fig. 3 is View invertical section on the line 33 of Fig. 2. Fir l is an elevational VlGWshown from the line ll oi 2. Fig. 5 is a further enlarged View insection on the line 55 of Fig. 2.

In the exemplilication of my invention shown in the drawings, thenumeral 10 designates a wall of a building located on a neck 12 to whichboat l lis tied up. A delivery pipe 16 leads through the wall 1 0 and issecured to the upper section 18 of a downwardly extending gooseneclrhaving a lower section 20 swivcled to the upper section. An upper boommember 22 and a lower boom member 24 are secured together at their innerends in tion 20, the lower end cl this section being a curved so to fitinto the member for different inclinations ot the latter. A. secondspout member 38 is telcscoped on the spout member 3st so as to becapable of sliding movement up and down thereon. A cable 40 secured atone end to the upper end of the spout member 38 and secured at its otherend to the lower end oi": this spout member passes over a pulley 42carried by the lower end or" the boom 24. The cable 40 serves tomaintain the spout member 38 at the desired inclination as it is slid upand down to change the length of the spout. Secured to the upper end ofthe spout member 38, tnere is a cable which passes over a pulley l6secured to the building. By pulling on the cable l the spout member 38will be slid upwardly on the spout member 34: and when the cable 'I-l isreleased, the spout member 38 will shde downwardly by gravity. In thismanner, the length of the spout i'uay be varied as l'ouud desirable.Secured to the outer end or? (lit boom 22, there is a cable 46 whichpasses over a pulley 48 secured to the building. By pulling on the cable46, the booms 22- and 2d will be raised and when the cable i6 isreleased the booms will lower by gravity. The spout members 34 and 38will be conjointly swung up and down with the boom members. The lowerportion of one of the cables as for instance the cable 46 winds on adrum 50 while the lower portion of the other cable as for instance thecable 4 lwinds on e. drum 52, these two drums being mounted in brackets54 secured to the building. The two drums are operated in the samemanner and hence a detailed description in regard to one of them may beconsidered as also applying to the other. lVorm gearing 56 is interposedbetween the shaft of the drum 50 and a shaft lib cured to the respectiveends ot a sleeve e8 which feathered on a shatt '70 a. iown in Fig. 5.The shaft is mounted 1 bearings '(Qhnd H as shown in 2 and 4t. Securedto the outer end of the 21 aft 70, there is a wheel 76 which is drivenby a belt or ch i drive 78 trained around a wheel carre" by the shaft ofa motor 82 as shown in 2. By referring to Fig. at, it will be understoodthat the lower drum 52 is adapted to be driven in a sin'iilar mannerthrough a bevel gear 62 engageable by bevel gears 6% and 66 secured to asleeve 68 feathered on a. shaft 70 which driven from the shaft 70 by a.sprocket chain 83. The sleeve 68 is engaged by the inner end of ashifter bar S-l while the sleeve 68 is engaged by the inner end of ashifter bar 86. The outer end ot the bar 8 is pivoted to a crank arm 88secured to a sleeve 90 rotatably mounted on a rotatable rod 92. A handle9-l secured to the sleeve 90 serves to rotate it and thereby br 1g oneor the other of the gears and (56 1.1..) engag mcnt with the gea 62according to the direction in which the handle 9&- is mo ed. The outerend of the bar 86 is pivoted to a crank arm 96 secured to the rotatablerod 92.

handle 98 secured to the rod 92 serves to ro- (ate it and thereby bringone or the other of the gears G l and 66 into engagement with the gear62 accordii a" to the direction in which the handle 98 i... moved. Byreferring to Figs. 2 and 3, it will be seen that the rotatable rod 92 ismounted in a bearing 100 inside the building and in a bracket bearing102 secured to the outside ot the b 1 and by reference to these twofigures a. well as to Fig. 1. it will be seen tl'iat the two handles 94and 98 are c ose toget -r outside of the building so that he pi or thespout member 538 may be readily observed and controlled.

The operation and advantages of my invention will now be obvious. Whenthe drum on which the cable a6 is wound is rotated in the properdirection, this cable will be pulled and the boom members 22 and 24-will be lifted around the pivot 28 as a center, thereby bodily liftingthe spout members 3% and 38 around the pivot 36 as a center. hen therotation of this drum is stopped, the be oms and spout members will bekept in the position into which they have been moved on account or" thewormv gearing acting as a stop. When this drum is rotated in the otherdirection to pay out the cable, the booms and spout members will swingdown under the action of gravity. When the drum on which the cable as iswound is rotated in the proper direction, this cable will be pulled andthe spout member 38 will be slid upwardly on the spout member 3a. henthe rotation of this drum is stopped, the spout member 38 will be keptin its upwardly telescoped position on account of the worm gearingacting as a stop. lVhen the rotation of this drum is reversed to pay outthe cable, the spout member 38 will slide down on the spout member 3 1by gravity. The shiilitable cable connection 4-0 permits the spoutmember 8G to slide in either direction while supported by the boom. Byproperly operating the two drums, the spout can be placed in any desiredposition for delivery ot material into the boat 0 other container. henthe spout is not in use, the cables at and i6 may be paid out so thatthe lower end of the spout member UK) will rest upon the dock and theboom may be swung around against the building on account of the swivelconnection between the two sections of the goose neck.

I claim:

I loading spout device comprising two boom members having their innerends socured together in angular relation in a vertical plane andpivotally supported for swinging movement in a vertical plane, anadjiiistable connection between the outer ends of said boom members, aspout pivoted at its upper end and consisting of telescoping members, apulley carried by the lower end of said boom members, a cable passingaround said pulley and having its two ends attached respectively to theupper and lower portion of the lower one of said telescoping members forsupporting said member from said boom, power-operated mechanism wherebysaid boom members may be raised and lowered to vary the inclination ofsaid spout, power operated mechanism whereby said spout may be more orless 'i'elescoped to vary its length, and means for independentlycontrolling the operation 0t said mechanisms.

In, testimony whereof I hereunto atlix my signature.

HENRY G. ONSTAD.
